This invention relates to improvements in spinning frames of a type generally known. In this well known type of spinning frame, as heretofore constructed, transversely arranged cast metal frames or sampsons are placed at suitable distances from each other throughout the length of the frame, the number of sampsons mounted in the frame depending upon the length of the frame and the number of spindles therein.

10 These cast metal sampsons are connected together by suitable framing members and support the spindle rails. In order to properly aline the mechanism of the spinning frame these cast metal sampsons are necessarily very carefully 1g machined and accurately alined throughout the spinning frame. This requires accurate manufacture and careful and accurate setting up of the frame.

In this type of spinning frame the reciprocal .20 vertical motion of the ring-rail, or builder mtion, is secured through the oscillation of cross shafts which are connected to the ring-rails by means of levers, the free ends of which have a reciprocal vertical motion and are connected to 25 the ring-rails by suitable rods. This form of builder motion results in imparting to the ringrail variable speeds in the course of its vertical movement. This variation in the speed of the movement of'the ring-rail is due to the fact 30 that the levers swing in an arc and move vertically faster at certain points in that are than at other points in the arc. Due to this variable speed in the movement of the ring-rail the bobbin or yarn package has a larger diameter at its 35 ends and a smaller diameter about the middle of the bobbin or yarn package. The smaller diameter at the middle part of the bobbin is due to the fact that because of the arrangement of the arms or levers which give vertical motion to 40 the ring-rail the ring-rail travels faster when at about the middle of the bobbin, or about midway the height of the spindle, and travels slightly slower when the ring-rail approaches the limits of its up and down movements. This defect 45 is increased as the traverse of the ring-rail is increased. Because of the variation of speed in the vertical movement of the ring-rail there is a variation in the tension on the yarn and this results in a rapid wearing out of the spinning 5n rings and the spindles.

It is the main object of this invention to produce a spinning frame free of the objections and disadvantages of the old and well known spinning frame as herein set forth.

Another object of the invention is to provide means whereby the ring-rail will be given a uniform and constant speed throughout its up-anddown movement or traverse.

A further object of the invention is to provide means whereby the length of the up-and-down 5 movement or traverse of the ring-rail may be varied in order to adapt the spinning frame for use with spindles of various lengths while at the same time producing a bobbin or yarn package of uniform diameter.

A further object of the invention is to provide means whereby the thread board carrying the thread guides is given a directly vertical up-and down movement at a constant uniform speed and in a definite ratio to the up-and-down travel of the ring-rail; to provide means whereby when the traverse of the ring-rail is varied the traverse of the thread board carrying the thread guides will be correspondingly varied while maintaining the desired definite ratio of travel between the thread board and the ring-rail.

A further object of the invention is to provide a construction of the spinning frame that will permit the manufacture of the parts in standard forms and lengths, whereby the spinning frame may be formed of any desired length for any desired number of spindles by merely assembling the standard parts in groups, the various supporting members being vertically adjustable on vertical standards of uniform shape in order to properly aline and level off all parts of the machine.

Another object of the invention is to provide vertical supporting standards which will serve not only as supporting elements for the machine and the parts thereof, but will also serve as guiding and supporting means for movable parts of the machine, such as the ring-rail and the thread board.

Other objects and advantages of the invention will appear hereinafter.

In the drawings, Fig. l is a diagrammatic elevation of a portion of the spinning frame constructed in accordance with my invention;

Fig. 2 is an end elevation of the head end of 4 the spinning frame construction illustrated in Fig. 1; and

Fig. 3 is a transverse vertical sectional view of the spinning frame constructed in accordance with this invention.

Referring to the various parts by numerals, I designates the head end of the spinning frame in which is mounted the mechanism for rotating the longitudinal shafts hereinafter described for imparting movement to the various mechanisms of the spinning frame. This mechanism is not shown as it forms no part of the present invention. Any suitable mechanism may be employed for driving the longitudinal shafts for imparting movements to the spindles and the other mechanisms hereinafter described.

The reference characters 4 designate vertical bars of any desired cross-sectional shape which form the standards or supports for the spinning frame. These standards or columns 4 are arranged in pairs transversely of the machine and the bars are located convenient distances apart from end to end. of the spinning frame. The lower ends of each pair of columns 4 are mounted in transverse base pieces or connecting bars 6, said bars being provided with sockets on their upper surfaces to receive the lower ends of the columns. Each base piece is provided with outwardly extending lugs at its ends and through said lugs are threaded leveling screws 6". The lower ends of these screws are provided with bearing plates adapted to rest on the floor in order to give an adequate support for the base piece. The upper ends of each pair of columns are connected together by a transverse bridge piece the upper ends of the columns fitting in sockets formed on the under surface of the bridge piece.

The sets of columns connected together transversely of the machine are connected together longitudinally of the machine by angle plates 5 secured to the ends of the bridge piece 5 and extending throughout the length of the frame. These angle pieces 5 form the bases or supports for the roll stands 5.

Rigidly secured to the standards or columns 4 are spindle-rail-supporting brackets 9. These brackets are formed with tubular sockets 9 adapted to closely fit the columns and are clamped thereon by bolts 9". The brackets extend outwardly from the sockets and the spindle rail 8 is bolted to the outer vertical faces of the brackets. The spindle-rail-supporting brackets may be vertically adjusted on the columns to place the spindle rail at the proper height and also to line it up horizontally throughout the length of the spinning frame. An outwardly facing spindle-rail bracket is mounted on each standard so that there is a spindle supported on each side of the spinning frame. The spindles are mounted on the spindle frame on suitable spindle bearings and are provided with the usual driving pulley over which the spindle-driving tape passes.

Secured to the under surface .of the spindle rails and extending transversely across the machine are a series of bars 21, said bars connecting together the spindle rails on opposite sides of the machine and serving as supports for the bearings of the longitudinally extending drum shaft 27.

On this shaft is secured the drum 2'!" around which the spindle-driving tapes 28 run. A tapetensioning device 28 is mounted on one of the spindle-rail-supporting brackets 53 for each spindle-driving tape, a weight 26 being provided to exert a constant tension on the tape through tape-tensioning means. This is common in spinning frames of this type and it is thought to be unnecessary to illustrate in detail the construction of the tape-tensioning device. It is manifest that by adjusting the spindle-rail-supporting brackets 9 up and down on the column 4 the spindles, the spindle-driving tapes and their tensioning means, and the tape-driving drum will all be moved together and without varying their relative adjustment with respect to each other.

Depending from the upper bridge pieces 6 are supporting brackets I I in the lower ends of which is journaled a longitudinally extending buildermotion shaft It. This shaft is given a rotary oscillating motion by suitable mechanism arranged at the head end of the machine. Any suitable automatically reversing means may be employed for this purpose and it is thought to be unnecessary to illustrate this mechanism. On the shaft l2 are secured a number of large ring-railmoving pulleys M which are spaced apart suitable distances along the shaft, the said shaft extending throughout the length of the spinning frame and the number of pulleys mounted thereon being dependent upon the length of the spinning frame. On the columns 4, above the spindle-rail-supporting brackets 9, are arranged vertical slides I6, said slides accurately fitting the columns and being arranged to slide up and down thereon. Near the lower ends of the columns and below the brackets 9 are arranged slides it which are similar to slides l6 and are adapted to slide up and down on the columns. Each pair of slides on each column is connected together by a vertical rod l1, said rod being arranged on the outer side of the adjacent column i. The slide it of each pair is connected by a chain E3 to a cooperating pulley M, the chain l3 running over a pulley l5 mounted in a bracket l5 connected to the top of the column and extending inwardly beyond the column. Connected to the upper end of the rod l'i just above the slide it is an outwardly extending ring-rail-supporting bracket l8. If! designates the ring-rail which is secured to the outer ends of the brackets l8 and normally lies above the spindle pulleys. There is a set of slides 16-46 for each column d, and each set of slides carries a rod IT and a ring-rail-supporting bracket E8.

The chain H from the ring-rail-supporting slide on one side of the machine contacts the pulley i l at one side of its center, while the chain l3 from the other side of the machine contacts the pulley It on the opposite side of its center. so that the rotation of the pulley M in one direc tion will result in the simultaneous upward movement of the ring-rails on opposite sides of the machine and the reverse rotation of the pulley [4 will result in the simultaneous downward movement of the ring-rails on opposite sides of the machine. The ring-rails are guided in their upand-down movements by the slides arranged on the columns 4 and said ring-rails move at a constant or uniform speed at all points in their travel both up and down. The extent of the up-anddown movement of the ring-rails is governed by the extent of rotation of the shaft I2. It is only necessary to provide means for rotating the shaft l2 a certain extent in one direction and then automatically reversing and rotating it the same extent in the opposite direction to provide the desired length of traverse for the ring-rails.

The thread board 21, carrying the thread guides 2! directly over the vertical axis of the spindle, is mounted on a series of vertically movable rack bars 24. These rack bars are mounted to slide upwardly and downwardly in guides formed in the outer face of the brackets 22 secured to the upper ends of the columns 4. Rotatabl'y mounted in each bracket 22 is a gear wheel 23 which meshes with the teeth of the rack bar. On the shaft of the gear wheel is mounted a small pulley 23' over which runs a chain 20, one end of said chain being connected to the pulley 23. The other end of this chain 20 is connected to and winds about a small thread-board-moving pulley l9 mounted on the shaft I2. The chain 20 from the pulley 23' on one side of the machine contacts the pulley!!! at one side of its center while the chain 20 from the other side of the machine contacts the pulley l9 on the opposite side of its center, so that the rotation of the shaft H in one direction will result in an upward movement of the thread board carrying the thread guides and the rotation of the shaft I2 in the opposite direction will result in a downward movement ofthe'thread'board.

The pulleys M and I9 are so proportioned with respect toeach other that the desired ratio of movement between the ring-rail and the thread board will be secured. The movements of the ring-rail and the thread board are controlled through'the rotation of a single shaft in order to secure the simultaneous reversal of movement of the two ring-rails and the two thread boards.

The brackets 22 supporting the thread boards may be adjusted on the columns t to locate the thread guides in proper relation to the upper ends of the spindles.

The ring-rails and the thread boards may be counter-balanced in any suitable manner, as is customary in machines of this type. Upon the reversal of the direction of rotation of the builder-motion shaft the ring-rails and the threadboards drop by gravity, the speed of the downward movement being controlled by the speed of rotation of the builder-motion shaft.
